Spring floods are hitting some parts of the country,
and the National Weather Service predicts high waters might hit
more states. Chuck Quirmbach reports:

There were record snowfalls in some northern, eastern and western states during the winter. Soil
moisture in some areas is very high. With the potential for spring rainstorms, the National
Weather Service says conditions are above average for flooding. Deputy Director Vickie Nadolski
says the threat will last a while.

“As you see the temperatures start to warm up in the summer, then certainly the ground will start
to dry out a bit more, but right now it’s quite saturated.”

Nadolski urges the public to listen to warnings of flash floods and river flooding. She warns
against driving or walking into flood waters.

The National Weather Service says soil moisture is not as high in states with prolonged droughts,
and that a lot of rain or snow there will bring temporary improvement to local reservoirs.

Lower Lake Levels: Multi-Causes

There’s more concern about lower water levels in the Great Lakes, both due to increased drainage, and possibly global climate change. Chuck Quirmbach reports:

There’s more concern about lower water levels in the Great Lakes, both due to increased drainage, and possibly global climate change. Chuck Quirmbach reports:


More data from a privately-funded study show long ago dredging on the Saint Clair River near Detroit may be one of the reasons for low water levels in Lakes Huron and Michigan.


Another study by the US-Canada International Joint Commission is looking at what to do about the higher flows out of the lakes. But hydrologist Roger Gauthier, of the Great Lakes Commission, adds a long warming trend to the list of factors affecting levels in Lakes Huron, Michigan and Superior:


“We’ve had below average snowfall. We’ve had very little ice cover in terms of thickness or duration. Much warmer lake temperatures.”


Less ice cover leads to more wintertime evaporation. Experts say trying to fix the drainage problem and control global warming should be goals.

Armadillos Migrating North

Armadillos are moving out of Southern states and are pushing into the
Midwest in record numbers. Adam Allington reports:

Armadillos are moving out of Southern states and are pushing into the
Midwest in record numbers. Adam Allington reports:


Prior to the 1900s, armadillos were hemmed in by large rivers and open
prairie grasslands that weren’t suitable habitat. Now, all that’s changed.
Humans have cultivated the kind of woodlands and thickets that armadillos
need for cover.


Lynn Robbins is a biology professor at Missouri State University:


We’re getting a lot more records in central Illinois, we’re getting more records up into
Nebraska, we’ve found them now moving up into Indiana… have no records so far in
Iowa, I would not be surprised if somebody called and said ‘yes, they’re here.'”


Robbins says warmer winters and lower average snowfall are one hypothesis
for the expanding armadillo range. They are also prolific breeders and have
no natural predators.

Lake Effect Snow Tied to Global Warming?

A recent study shows a possible link between global warming and lake
effect snow. The Great Lakes Radio Consortium’s Richard Annal has more:


The study was published in the Journal of Climate. When compared with the rest of the nation,
researchers found that the Great Lakes region had a significant increase in the amount of
snowfall.


Adam Burnett is an Associate Professor of Geography at Colgate University. He was the lead
researcher of the study. Burnett found that Warmer lake temperatures make ideal conditions for
lake effect snow.


“As cold air begins to blow across these warm lake surfaces that sets up the lake effect snow
processes. And the thinking is that perhaps global warming is being reflected by increases in the
thermal characteristics of the Great Lakes, which are then playing out in the Great Lake effect
snow.”


In the study, Burnett compared the snowfall from fifteen weather stations around the Great Lakes.
He examined records going back over seventy years. Syracuse, New York is one of the nations
snowiest cities. In terms of the amount of snowfall, it had five of it’s worst winters on record in
in the 1990’s, the warmest decade of the twentieth century.

La Nina May Bring Hard Winter

If you enjoyed the milder than normal winters we have enjoyed for the past two years, BEWARE: some climate researchers think we may be headed for a cold winter, with heavier than normal snowfalls. The Great Lakes Radio Consortium’s Bud Lowell has more:
